Con: electric connector; Pos: positioning key

Table 1 has shown that positioning key is changed to a cover electric connector of 40 from 31, in order to prevent that electric connector 31 and other electric connector from mismatching, core of the present invention is after elected middle unit " A " disposes electric connector as an independent positioning key, unit " A " can be not again occur in any one group of location of in 32 to 40, so can prevent mismatching of electric connector 31 and other electric connector.

In order to prevent to be mismatched with electric connector 31,33 to 40 by the electric connector 32 of unit " BC " configuration, unit " BC " can not be repeated to be selected in two continuous positioning keys, as: Pos1,2, Pos2,3, Pos3,4, Pos4,5, Pos6,7, Pos7,8, Pos9,10.Correspondingly, electric connector 32 can not dock with other connector yet.The rest may be inferred can be with ten equal logic configurations of electric connector, thereby can not mismatch between electric connector.

In addition, each formation unit 21,22,23,24,25,26,27 and 28 all has the complexity of corresponding note " A, B, C, D, E, F, G and H " with science, logically simplification formation unit 21,22,23,24,25,26,27 and 28 geometrical combination in the present invention.Use method of the present invention, RE37, Fig. 3 of No. 296 patents can represent that it explains that clearly electric connector 12,78,80,16,82,84,86,88,92,94 and 96 each other can wrong reason of docking by the formation of Fig. 4 of the present invention.

Regard electric connector 12 as A, electric connector 78 is regarded GF as, electric connector 80 is regarded EEG as, and electric connector 16 is regarded BEHE as, and electric connector 82 is regarded EHGGD as, electric connector 84 is regarded HHHBEH as, electric connector 86 is regarded FFHHECF as, and electric connector 88 is regarded HFDHEGHH as, and electric connector 90 is regarded BDEGEEHHB as, electric connector 92 is regarded EGGHFEGHEC as, and electric connector 94 is regarded HDGHEGHEEEF as and electric connector 96 is regarded HHEHEEEFGEHH as.

In fact, when the designer uses method of the present invention, can design the many groups of electric connectors that can not dock mutually, now describe with following formula. $\mathrm{Events}=E^n-\underset{i=n-1}{\overset{1}{\mathrm{\Σ}}}(n-i+1)E^i$

Wherein:

N: the number of electric connector positioning key;

E: the number of unit that constitutes electric connector;

Events: the combination that all unit are set up by all positioning keys.

E ⁿ: the combination that all unit that all unit constitute by " n " individual positioning key are set up. $\underset{i=n-1}{\overset{1}{\mathrm{\Σ}}}(n-i+1)E^i:$ The combination that all repeat to set up.

If electric connector 31 and 32 is established as gang, we need at first to determine what alternative unit electric connector 31,32 has, and uses above-mentioned formula then so.Earlier from the unit " A, B, C, D, E, F, G and H " of electric connector 31, select a unit arbitrarily, select arbitrarily from the unit " A, B, C, D, E, F, G and H " of electric connector 32 then and unduplicated any two unit of the module of selection of electric connector 31, electric connector 31,32 can obtain 48 groups of combinations altogether as shown from the above formula.

Use the above-mentioned formula of the present invention, can make the designer without hesitation electric connector be carried out science, logically design.
